The german Support from BMS tell me to change the coils and spargs, what i did. but i had the same issues after put new.
After desperation I decidet to get the Box out of my car and do a reasonable ecu tune. I chose Manhart, because i heard only positive about them and the tuner is in the same city where i stay. (In Germany)
Now my M6 run without issues and a lot of power. Before i get the JB4 i heard a lot of negative experince about tuning boxes and now i can confirm it! Thats the first time that a put a tuning box in my car and i will never put a box in my cars again. Only ecu tune !!!
And the Clutch does not slip anymore. I'm so happy to drive my m6 without problems.
Sorry for my bad english but i wanted to tell you guys my experince with
